[SOLVED]WiShield and DS1307+ (Wire.h conflict)

hello,
i have problem use arduino uno r3 + wifi shield + rtc ds1307.
i use asynclab library wifi , rtclib ds1307. problem after add #include "wire.h" - request dont return correct data:
returned data included wire.h:

code: [select]


got connection cpd.as-to.eu
connected cpd.as-to.eu
tx 72 bytes
0 - 71 of 72
rx 0 bytes cpd.as-to.eu
rx 324 bytes cpd.as-to.eu
http/1.1 200 ok

vary: accept-encoding
content-length: 112
connection: close
c
got connection cpd.as-to.eu
ended connection cpd.as-to.eu

and returned date without included wire.h(this correct/complet):

code: [select]

may 11 2012
ended connection cpd.as-to.eu

and usre return function getrequest:

code: [select]

// function prints data server
void printdatatime(char* data, int len) {
 datastring="";
 while (len-- > 0) {
   //serial.print(*(data++));
   datastring += *(data++);
 }
 serial.println(datastring);
 if(datastring.indexof("#date:")!=-1){date=datastring.substring(datastring.indexof("#date:")+6,datastring.indexof(":date#"));}
 if(datastring.indexof("#time:")!=-1){time=datastring.substring(datastring.indexof("#time:")+6,datastring.indexof(":time#"));}
 if(datastring.indexof("#unixstamp:")!=-1){unixstamp=datastring.substring(datastring.indexof("#unixstamp:")+11,datastring.indexof("#unixstamp:")+21);}
 if(datastring.indexof("#source:")!=-1){source=datastring.substring(datastring.indexof("#source:")+8,datastring.indexof("#source:")+13);}
 serial.println(date);
}

wifi shield futura eletronica(with chip mrf24wb0ma),  and ds1307+ its:

thanks much.

you don't have lot of memory on arduino. wire library needs some. wifi library needs (a fair amount, actually). string class (that don't need using) needs more it's fair share.

and, yet think problem in conflict in wire.h? why?

before added wire.h, how communicating rtc? why necessary change?
